hi, I'm wondering whether bird's RIP implementation features keys of limited lifetime, as the protocol dictates: From RFC2082: Implementations MUST support the storage of more than one key at the same time, although it is recognized that only one key will normally be active on an interface. They MUST associate a specific lifetime (i.e., date/time first valid and date/time no longer valid) and a key identifier with each key, and MUST support manual key distribution (e.g., the privileged user manually typing in the key, key lifetime, and key identifier on the router console). The lifetime may be infinite. I've tried to use the 'generate to/from' 'accept to/from' syntax, but didn't work. The authentication always fails. regards, al_ex ____________________________________________________________________ http://www.freemail.gr - δωρεάν υπηρεσία ηλεκτρονικού ταχυδρομείου. http://www.freemail.gr - free email service for the Greek-speaking.
